One small thing I don't think is quite right. You say em is relative to the current element's font-size, but I believe it is actually the parent element's font-size. Which is why it can lead to unexpected results.
In the example in MDN Docs, h1 element inherits line-height: 1.1em from its parent div element; Only in such circumstance the computed line-height of h1 would be 1.1 * its parent element's font-size;
